Tetra­kis[μ-4-(dimethyl­amino)benzoato-κ(2) O:O′]bis­[(N,N-diethyl­nicotinamide-κN (1))zinc(II)]

The title mol­ecule, [Zn(2)(C(9)H(10)NO(2))(4)(C(10)H(14)N(2)O)(2)], is a centrosymmetric binuclear complex, with Zn atoms [Zn⋯Zn′ = 2.8927 (4) Å] bridged by four carboxyl­ate groups from the dimethyl­amino­benzoate (DMAB) ligands. The four carboxyl O atoms around the Zn atom form a distorted square-planar arrangement; the distorted square-pyramidal coordination geometry is completed by the pyridine N atom of the N,N-diethyl­nicotinamide (DENA) ligand. The Zn atom is displaced by 0.3326 (2) Å from the plane of the four O atoms, with an average Zn—O distance of 2.0416 (12) Å. The dihedral angles between the carboxyl­ate groups and the adjacent benzene rings are 5.31 (8) and 11.00 (9)°, while the pyridine ring is oriented at dihedral angles of 66.26 (6) and 37.88 (7)° with respect to the benzene rings. Weak intra­molecular C—H⋯O and inter­molecular C—H⋯π inter­actions are present.
